Example:
Frictionless air flow in the vicinity of an aircraft.
The flow equations in Eulerian formulation reduce to
Euler derivative: laboratoryfixed coordinate system;
at a fixed point in space
Lagrange derivative: properties of a volume element
that is moving along with the flow;
Lagrange form of the flow equations:
where the last equation may be written
(see 8.4),
